I recently hired a commercial lab to replicate the FeBr2 + Cu(OH)2 Differential Scanning Calorimeter experiment that Mills and his validators have reported. It works. I'm shopping a paper around to journals, but you can see a preprint along with my spreadsheet calculations and the report from the lab here. Based on the assumed reactions that Mills et al have used, the signal was 100% excess energy compared to conventional chemistry. This despite an error I made: the FeBr2 was ordered as beads not powder, so the mixing was poor. I expect repeating this with powder for both reagents will show even more excess energy.
The lab did all handling of materials from ordering, preparing the sample, running the instruments, and producing a final report from which I plugged numbers into my spreadsheet. Those who have accused Dr. Mills of fraud are going to have to explain why this commercial lab, likely never having heard of GUTCP/Mills/hydrino (they didn't hear it from me), is in on the conspiracy.
